I have two synchronized DACs AD9122 on two different PCBs (same reference clock). For testing, I want to drive the DACs with one DPG.
1) DPG has TXI and TXQ data available so I can drive each DAC with each set of data.
2) DPG has CLK_TXI and CLK_TXQ so I can drive DCI signal of each DAC
3) DPG has CLK_DCOA and CLK_DCOB. Assuming that my two PCBs use the same reference clock to build the sampling clock on each board (synchronized AD9516), CLK_DCOA and CLK_DCOB should be similar.
Then I can use only one DPG.
Am I correct? Is there something missing?
Thank you for your help.
